HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent N0. 748,382, dated December29, 1903. Application filed December 9, 1902. Serial No. 134,523. (Nomodel.)

To all whom it may concern: I

Be it known that I, WOLFGANG KOLLER, a citizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania,have invented certain new and useful Improvements in Hose-Couplings, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to certain new and useful improvements inhose-couplings, and has for its main object to provide novel andeffective means for quickly and efiectively joining two sections ofhose.

Briefly described, the invention comprises two abutting collars, one ofwhich is mounted on one section of the pipe and the other of which ismounted on the abutting end of the other section of the pipe to becoupled. These collars carry a pair of pivoted latches, one oneachcollar and each of. which is provided with a spring-pressedlocking-bolt, and these latches engage with studs or pins carried by thecollars. provided on its engaging face with a gasket countersunk intothe face of the collar to prevent any danger of leakage between the twocollars.

All of the above construction will be hereinafter more specificallydescribed and then particularly pointed out in the appended claim, andin describing the invention in detail reference will be had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference will be employed for indicating like partsthroughout the different views, in which Figure 1 is adetail perspectiveview showing my improved coupler in the coupled position. Fig. 2 isaside elevation of the same. Fig. 3 is-a like view of the couplerreversed. Fig. 4: is a longitudinal sectional view. Fig. 5 is a detailperspective view of one of the pivoted latches, and Fig. 6 is alongitudinal sectional view thereof.

To put my invention into practice Iprovide two collars 1 and 2, theformer mounted securely on the end of the section 3 of the pipe and thecollar 2 mounted securely on the engaging end of the section 4 of thepipe..

One of the collars is preferably The collar 1 is provided in itsengaging face with an annular groove or recess, and in this groove orrecess is seated a flexible gasket 5 ofa depth suffici'ent to projectslightly beyond the face of the collar 1 until the collar 2 is engagedfirmly therewith to compress the gasket. The collar 1 has pivotedthereto, on one side thereof, a latch 6, provided with a hook end 7,which is adapted to engage with a pin or stud 8, carried on the collar2. The collar 2 likewise carries a pivoted latch provided with alocking-bolt, the latches of the two collars having their hook endsextending in opposite directions. In order to prevent accidentaldisengagement of the latches from the pins orstuds, I provide each ofthe latches with aspring-pressed locking-bolt 9, mounted in a recess 10,provided therefor in the face of the latch, and backed by thecoil-spring 11. For convenience in operating, each locking-bolt ispreferably provided with a small knob 12.

In practice I preferably mount the collar 1 on its pipe projectingbeyond the end thereof and mount the collar 2 on its section of the pipesome distance back from the engaging end of this section of the pipe.The joint between the two sections of the pipe will therefore be withinthe collar 1, as clearly seen in Fig. 4 of the drawings, and should anyleakage occur between the ends of the two pipesections the gasketprevents same passing out between the two collars.

It is to be noted that, the latches being pivoted to opposite sections,should one become accidentally detached the other will still hold thesections together.

It will be perceived that the latches are mounted to have a verticalrotary movement in a plane transverse to the sections, which has theadvantage of obviating to a greater degree the liability of the latchesbecoming disengaged by encountering obstructions or the like in draggingthe hose along the ground than were a different mounting of the latcheseffected-such, for instance,'as mounting the latches so as to have amovement in a plane transverse to the longitudinal axes of the sections.

While I have herein shown and described the invention in detail as it ispracticed by me, yet it will be evident that various slight changes maybe made Without departing from the general spirit of the invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In combination with the hose-sections having their ends in abuttingengagement, a collar carried by one section and extending beyond the endthereof, said collar having a groove formed therein with a gasketseating' in said groove, a collar carried by the other section andlocated to the rear of the end thereof and adapted to abut thefirstnamed collar at a point to one side of the joint H.
